%% Note on function definition
%%   included is all defined plugin function
%%   it's possible not to define some function at all
%%   in that case, warning will be generated at compilation
%%   and function call will fail,
%%   then mod_pubsub will call function from node_default
%%   (this makes code cleaner, but execution a little bit longer)
